Getting in and out of the water is the unsafe part in raglan that might give you a few scratches, the locals are fine, as long as you give respect and are not an idiot and stick to surf etiquette( same applies to any beach in the world)

It's just when getting in and out of the water, and even that can be avoided by making a longer paddle to a boat ramp further down ( If it's still there, it's been 15 years since I was there)
It's a great town.
